Best VPN to download on iPhone/iPad

what would you recommend as the most secure VPN to download on iPhone/iPads? I am trying to run away from the risk of the provider using all info I am having and working on through my mobile devices. I travel a lot and I want to make sure that when connected to wi fi I can turn my VPN on and securely have it functioning.

it's good enough.
this one is not free, but will give a full solution if you are willing to pay:http://www.ibvpn.com/product/
